Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed November 29, 1904;. Serial No. 234,712.

' One of the objects thereof is to provide a simple and efficient form of hoisting apparatus which shall be positive and reliable in action.

Another object is to provide an apparatus of the above type which is particularly adapted for use in elevating and transferring live stock, especially hogs.

Another object is to provide means whereby the live stock or other object to be elevated can be positively and yet detachably connected to a supporting member.

Another object is to provide elevating means of the last mentioned type whereby the necessity of transfer of the object to be hoisted from one supporting member to an other, with the disadvantageous features attendant thereon, is obviated.

- Other objects will be in part obvious and in part pointed out hereinafter.

The-invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the apparatus hereinafter described and the scope of the application of which will be indicated in the claims at the end of this description.

In the accompanying drawings wherein is shown one of the various possible embodiments of my invention, Figure 1 is an elevation of the same. Fig. 2 is a detailed perspective view of certain parts thereof.

Similar reference characters refer to similar parts throughout the several views.

In order to render clearer the general nature of my invention, it may here be noted that it is a desirable feature in many types of hoisting apparatus, to attain a continuously and positively acting means of elevation. In this manner the chance of slipping of the parts is reduced and the certainty of operation increased, and the necessity for starting and stopping the elevating means with consequent labor and loss of time, is obviated. Another desirable feature in such apparatus is the provision of means for making a detachable connection therewith whereby the object to be raised may be readily connected and disconnected from the elevating apparatus and yet may be positively locked in position. The latter is of particular value when apparatus of this type is used in connection with live stock on account of the likelihood of struggling and consequent chance of disengagement of the object to be hoisted. It may also here be noted that in the use of hoisting apparatus in the above connection it is of marked value to provide a connection with the supporting member which will not swing with relation thereto, as the same is thus rendered less likely to become detached or the animal to swing from the desired position. Moreover, in hoisting apparatus as applied to live stock, it would obviously be a feature of marked value if the necessity of transferring the hog or other animal from one supporting member to another were obviated. The above and other advantages are attained in constructions of the nature of that hereinafter described.

Referring now to the drawings wherein my which is mounted a supporting member 2 preferably round in cross section. This member comprises a horizontal portion 3 rigidly supported upon support 4, an u wardly inclined portion 5, and a downward y inclined portion 6. At the uppermost point the supporting member 2 is supported by means of a rigid hook shaped rod 2 as more clearly shown in Fig. 2 of the drawings. It will be obvious that more of the supporting rods may be used if needed.

Journaled upon support 4 is a heavy sprocket wheel 7 supporting a chain 8 which passes over the co-acting sprocket wheel 9 adjustably mounted from the framework 10 of the building. This adjustment is preferably accomplished by journaling the shaft 11 of the sprocket wheel 9 within the bearings 12 slidably mounted in frames 13. A heavy screw 14 passes through the frame 13 and engages the bearing 12 and holds the same therein in any desired position. Chain 8, which is guided so as to run substantially parallel to the portions 3 and 5 of the supporting member 2 by means of a guide 15 provided with rollers 16, comprises a series of alternate long and short links 1'2. and 18,

the latter of which are each provided with an outwardly projecting arm 19. At the end of each arm 19 is what may be termed a rider or dog 20 adapted to straddle and fit the supporting member '2, as shown in Fig. 2 of the drawings, and provided with lugs 21 for a purpose hereinafter described. Also secured upon the end of arm 19 is a forwardly projecting locking arm 22, the end of which is so shaped that when in operative relation with supporting member 2, it curves away therefrom, as shown in Fig. 2 of the drawings. The term arm as used at certain places throughout the following claims is intended to comprehend not only the arm 19 proper, but also rider 20 and arm 22 which may be formed thereon instead of connecting there with, if desired.

The links of chain 8 are oined in any desired manner so as to rovide a flexible connection. The term exible member however, is used throughout the following claims in a broad sense as comprehendin not only a chain, but a belt or other equivaTent for the same.

Detachably mounted upon supporting bar 2 are two pronged hooks 23 which fit member 2 and are provided with upwardly projecting end portions 24, for a purpose hereinafter described. By the term prong as used throughout the following claims in relation to a hook, is meant a projecting part of the same adapted of itself to engage the supporting member; thus, in a two pronged hook there are two substantially identical parts, each of which engages the supporting member, thus providing a double bearing for the same. Inlike manner a multi-pronged hook would be provided with any desired number of prongs accomplishing a similar object. The lower end of hook 23 terminates in an eye 25 with which the object to be hoisted may be connected as by means of chain 26.

Although the hoisting apparatus herein shown appears as applied to live stock or hog hoisting, nevertheless the invention has a broad application for the purpose of hoisting or transporting any desired articles. There are, however, several advantages peculiar to the use of this invention in connection with live stock hoisting.

The operation of the above described embodiment of my invention is as follows: The sprocket wheel 7 or 9 being driven in the desired direction from any source of power, theoutwardly projecting arms 19 travel in operative relation to the portions 3 and 5 of the supporting member 2, as shown in the drawings, the direction of travel being indicated by the arrow appearing in Fig. 1. The article to be hoisted is first made fast to the hook 23 which is thereupon thrown into engagement with the supporting member 2 at any part of the horizontal portion 3 thereof and passes between the end of the locking arm 22 and the rear surface of the next preceding arm. The travel of the chain causes the curved surface of locking arm 22 to engage one side of the upwardly projecting portion 24 of hook 23 and thus wedges the same securely into engagement with the support ing member and prevents accidental detachment thereof. This locking engagement is shown more clearly in Fig. 2 of the drawings.

' Upon the engagement of lugs 21 with the lateral surface of the hook, the latter is forced forward and upwardly along the inclined portion 5, the object attached thereto being transported and raised from the surface upon which it was placed. Upon reaching the upper extreme of portion 5, the hook 23 is automatically released by reason of the di vergence between the supporting member and the locking arm at this point, and the same being forced over the summit or highest point of supporting member 2 and transported by its own weight along the clownwardly inclined portion 6 to any desired destination.

In the embodiment shown, the apparatus appears in connection with hog hoisting, the hook being made fast in the above described manner, as shown in the drawing, and raised as above set forth. Upon passing the highest point, the hog, together with the hook attached, slides down the inclined portion 6 which in this case is a sticking rail, and is in ent that the other features hereinbefore' mentioned as desirable in connection with this type of apparatus are attained to a marked degree. I desire it also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of lan-- guage, might be said to fall therebetween.
